Grease trap & FOG requirements
Under UPC, food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. A grease interceptor sized to the state plumbing code is required, with a municipal sewer-authority FOG discharge permit.
Hood fire suppression (IFC): commercial cooking under a Type I hood needs a wet-chemical suppression system to NFPA 96, permitted and inspected by the local fire marshal. Commercial hood suppression must meet NFPA 96 and the state fire code enforced by local fire officials. See do I need a hood? and the hood CFM calculator.
Backflow prevention: An approved backflow preventer with a certified annual test is required by the local water purveyor. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
